Step 1: Prepare Your Mould

The first step in creating clear resin objects is selecting or making the right mould. Silicone moulds are preferred for their flexibility and detail. If you want a custom shape, consider creating your own using “Liquid Mould” – Casting Liquid Silicone Rubber, 5-40 Shores, Bi-Component A+B. Ensure the mould is thoroughly clean and dry before use; any dust or moisture can impact the final clarity of your piece. For complex or delicate shapes, a high-quality silicone mould will help achieve crisp details and easy demoulding.

Step 2: Mix the Resin Carefully

Refer to your chosen resin’s instructions for exact mixing ratios. Accurate weighing and combining Part A and Part B is critical. Mixing too quickly can introduce bubbles, so stir carefully and scrape the sides and bottom of your mixing vessel. Accurate measurements and thorough mixing prevent curing failures. If you’re working with layers thicker than 2cm, select a product such as “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm or “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting, following their specific deep-pour recommendations.

Let mixed resin rest a few minutes to allow trapped air to escape before pouring. If you see surface bubbles, a quick pass with a heat gun or hairdryer (on low) can help eliminate them. Do not overheat, as this can cause yellowing or create uneven cures.

Step 3: Pour and Cast the Resin

Slowly pour the mixed resin into your mould, starting at one corner and allowing it to flow naturally to reduce the risk of air pockets. For projects requiring maximum clarity, pour in a thin, continual stream and avoid unnecessary agitation. Avoid pouring layers too thick for your chosen resin: for example, “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm should not exceed 2cm per layer, while specialised deep-pour epoxies can go thicker as directed.

Ensure your workspace is level to keep the resin surface even. Once poured, cover your piece with a clean box or dome to prevent dust from settling while curing.

Step 4: Cure and Demould Your Object

Allow the resin to cure undisturbed for the full recommended time—often 24–72 hours depending on product and thickness. Curing at temperatures between 20–25°C is ideal. Patience here delivers the best, clearest results. Once fully set, gently remove your object; silicone moulds simplify this step. Let your resin cure fully before demoulding to avoid fingerprints, cloudy finishes, or warping.

After demoulding, edges can be sanded or polished as needed for a professional finish.

Tips, Troubleshooting, and Common Mistakes

Maintain a dust-free working environment and avoid high humidity, which can cause surface blemishes. Pour within the suggested thickness range for your resin, as excessive thickness may cause overheating or incomplete cures. Always measure accurately and mix thoroughly. If bubbles persist, a light heat application usually helps, but overuse can damage clarity. For the best shine, allow each layer to set before adding more, and wait for the resin to fully harden before sanding or polishing.
